Electricity usage advice

Energy28

Hello
I've been taking my electricity readings each month and could do with an opinion on if my usage seems fair?
I'm an electricity only house, 3 large storage (old) heaters, 3 newer, but old style, 1.5kw versions. Fan heater in the bathroom and 2 coal files. All double glazed, mid terrace, no cavity extension that holds the bathroom, utility and Kitchen.
I am on econony 10 for NSH and hot water. 5 hours at night, 3 hours in the afternoon and 2 in the evening and of course can use appliances in these times on the off peak rate. I'm with EON, 13.5p per KW off peak (inc vat) and 23.5p per KW peak (inc vat) and a standing charge of 22p per day.  I think that is everything.
Over the last month with NO heating on the off peak was £1.95 per day, and peak was £1.44 per day and then the standing charge. Does this seem a fair usage? In the height of winter we usually spend a similar peak rate, but £7.60 per day for Off peak. It's been over 30 years since I've had a gas system so am out of touch with if the cost I am paying is fair?

We have nowhere to put an oil or LPG tank, air system and no direct mains gas in the village, so need to stick with electric sadly. 

Taking away the initial outlay of new style NSH, are they cheaper to run? Bearing in mind we use off peak for water throughout the day, is E10 worth sticking with? 
Your opinions  on my daily cost  and of its reasonable and any ideas of if an upgrade is a good idea on E7 or E10 and if E7, options for hot water. Any recommendations for NSH brands worth looking at.

Advice welcomed (other than moving house 😊).
TIA

That's a very expensive tariff.  I've just signed up to a single rate 13-month fix at 12.977p/kWh, Daily Charge 10.00p. Do the sums !

But it's with Symbio, so it could be a bumpy ride...

Modern high heat retention NSHs don't waste so much heat overnight so are likely to be slightly cheaper to run, but the payback period could be lengthy.

You might be better off switching to a competitive E7 tariff from a cheap supplier and adding an extra NSH if it's gets chilly in the evenings.

Night storage heaters are 100% efficient in turning electricity into heat. Newer ones won't gain you much (they might be a little bit better at keeping the heat in when you don't need it and letting it our when you do).

Converting your numbers into kWh:

• Summer: 6.1 kWh peak & 14.4 kWh off-peak per day
• Winter: 6.1 kWh peak and 56.3 kWh off-peak per day.

That sounds a little high but not terrible, about 30% more than I use in a 1950s three-bed semi with cavity walls and reasonable insulation.

Your electricity tariff seems to be on the expensive side, though. There are single-rate tariffs where the 24-hour rate is similar to your off-peak. Have you done a recent comparison?

Edit: I see Gerry1 types faster than I do!

Thank you both. Can I run NSH off a single rate tariff? Also would I need a new type of hot water cylinder?

Yes, you can run an NSH on a single rate tariff without even needing a meter change.  E.On are obliged to offer this, although their single rate will probably still be quite expensive.  However, there will only be one standing charge.

You won't need a new tank, but if you had just one immersion heater on an E10 circuit and switched to E7 you might want to have it rewired with a local timer on a 24h circuit in case the water gets cool in the evening without the E10 afternoon boost.
